Generate constructors for frog DOM

Generate constructors for frog DOM

Note, this overlaps with the other CL (http://codereview.chromium.org/8595020/) as the underlying IDL has changed.

Stephen: If this looks good, I can autogen the wrapper templates as well.

File client/dom/generated/src/frog/WebKitCSSMatrix.dart (right):

http://codereview.chromium.org/8569017/diff/2001/client/dom/generated/src/fro...
client/dom/generated/src/frog/WebKitCSSMatrix.dart:3: WebKitCSSMatrix([String
spec]) native;
It is not clear how this can be made to work on non-webkit browsers (where the
type is CSSMatrix http://www.w3.org/TR/css3-3d-transforms/#cssmatrix-interface)

I think the factory provider syntax at least allows delegation to some code that
can create a CSSMatrix.

John: what do you recommend?

The native code might look something like this:

if (defined CSSMatrix)
  return new CSSMatrix(spec);
else
  return new WebKitCSSMatrix(spec);
